"Recently Haas et al. (J Neurophysiol 96:
3305–3313, 2006), observed a novel form of spike timing
dependent plasticity (iSTDP) in GABAergic synaptic
couplings in layer II of the entorhinal cortex. Depending
on the relative timings of the presynaptic input at
time tpre and the postsynaptic excitation at time tpost,
the synapse is strengthened (delta_t = t(post) - t(pre) > 0) or
weakened (delta_t < 0). The temporal dynamic range of
the observed STDP rule was found to lie in the higher
gamma frequency band (> or = 40 Hz), a frequency range
important for several vital neuronal tasks. In this paper
we study the function of this novel form of iSTDP in
the synchronization of the inhibitory neuronal network.
In particular we consider a network of two unidirectionally
coupled interneurons (UCI) and two mutually
coupled interneurons (MCI), in the presence of
heterogeneity in the intrinsic firing rates of each coupled
neuron. ..."
